SPECIFICATION forming part of Letters Patent No. 672,362, dated April16, 1901.

Application filed November 14,1900. Serial No. 36,539- (No model.)

To rtZZ whom it mat concern:

Be it k nown that I, FREDRICK HENRY SPARE llAwLEY, a citizen of theUnited States, and a resident of Pretoria, South African Republie, bu tat present residing at Durban, Natal, have invented a new and usefulImprovement in Metal Ceilings, of which the following is a full, clear,and exact-description.

One purpose of the invention is to simplify and chcapen the work oferecting metal ceil' ings by so constructing the plates or panels thatthey may be quickly and systematically laid upon a foundation consistingof two series of fnrring'strips, one series being at angles to the otherseries of furriug-strips and the upper series resting upon the uppersurfaces of the furring-strips of the lower series, thereby dispensingwith the necessity of recessing and interlocking the said strips.

Another purpose of the invention is to so form the plates or panels thatthey may he laid in the same horizontal plane upon a ceiling structureof the character described and seen red thereto in a convenient manner.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both figures.

Figure 1 is a perspective View of a portion of a ceiling constructed inaccordance with my invention; and Fig. 2 is a vertical section throughthe ceiling, the section being taken transversely through the floorjoists or girders and through the furring-strips extending parallel withthe floor joists or girders, and the section being likewise takentransversely through plates attached to the furring-strips.

A represents the floor joists or girders of a structure, upon thebottom' portion of which furring-strips 10 are secured, extendingtransversely across the girders, as shown in Fig. 1, and another seriesof furring-strips 11 is attached in any suitable or approved manner tothe under face of the furring-strips 10, the two series offurring-strips being at angles to each other.

The plates or panels B, shown formed from a continuous strip, are laidupon and secured to the structure above mentioned, and the panels aresupported by grooves 12, which grooves produce offsets 13 at the frontfaces of the panels at opposite sides, so that the body portion of eachpanel or plate B is sunken or in intaglio. The grooves are so made thatthey accommodate and neatly receive the undermost furring-strips 11, asshown in the drawings, so that the body portions of the panels may bebrought in engagement with the uppermost furring-strips 10 and securedthereto by nails, tacks, or their equivalents.

In order that the plates or panels B may be systematically laid out atthe opposite edges of each plate or panel, a transverse offset 14: isprovided, corresponding to the side offsets 13 and connecting therewith,the opposite transverse edge of each plate or panel being left plain, asshown in Fig. 1; but if it be desired to make a double panel the transverse offset 14 is placed at the central portion of the panel, or at apoint about centrally between its ends, and the side offsets 13 extendfrom end to end of such double panel. Under this construction it isobvious that the foundation for the panels-namely, the furring-strips 10and 11--need not be recessed or mortised, so as to interlock, and underthe improved construction the foundation for the panels or plates may bemore quickly and securely erected than under the usual construction. Thepanels are illustrated as provided with offsets 15 between the groovedoffsets at the sides; but it will be understood that the said offsetsare simply in the nature of decorations and may be omitted if it befound desirable.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In metal ceilings, two series of furringstrips oneseries being at angles to the other series, the furring-strips of theupper series resting upon the upper surface of the furringstrips of thelower series, and plates or panels having offset portions forminggrooves, which grooves receive the furring-strips of the lower series,the body portion of the panels being arranged to engage with the upperseries of furring-strips and adapted to be secured thereto, asdescribed.

2. In metal ceilings, two series of furringstrips one series being atangles to the other series, the furring-strips of the upper series beingsupported upon the upper surface of the furring-strips of the lowerseries, and plates or panels having offset edges forming grooves, whichgrooves receive the furring- 1o strips of the lower series, the bodyportions of the panels or plates being in intaglioand adapted forattachment to the furring-strips of the upper series, as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
